To all whom it my concern:

Be it known that I, FnANgIs ALBERT Ponon'r, a citizen of the FrenchRepublic, and resident of Paris, France, have invented certain new anduseful Improvements in Casting Machines for Siphon Heads, of I which thefollowing is a specification.

My invention relates to casting machines for siphon heads in which theseveral parts, comprising mold parts and cores, are held in operativerelation to each other in a mannet that certain of the cores maybemechanically removed from a position coacting with mold parts in orderto expedite the manufacture of, facilitate the removal of the finishedproduct and automatically return the cores to a position in operativerelation to the mold parts.

The objects of my invention are to make a complete casting with theleast complicated mechanism, to provide a device simple in constructionand operation, whereby its use reduces the cost of such castings, and toso dispose the several parts that they may be maintained at the desiredtemperature by a source of Heat such'as a blowpipe. I

arrangement of parts shown in the accompanying drawings, in which,-

Figure 1 is a central vertical section of a device embodying myinvention, as seen from the side. Fig. 1 is a sectional detail of aportion of the base coreactuating mechanism. Fig. 2 is a centralvertical section taken on the, line 22 of Fig.1, a fg mmetrical-portionto the right bein inicated by dotted lines. Fig. 3 is a etail sectionalview through a portion of the clamping means for the mold parts.) Fig. 4is a detail view showing the mechanism for imparting movement to certainofthe core members.

Similar reference characters refer to similar arts throughout theseveral views.

The ap aratus comprises asuitably supported ta le 1, upon which moldparts 3 are symmetrically mounted and centered by means of the flange 1formed on the table and serving as the bottom margin of the mold. Thesepattern plates 3 are movable and are operated by means of handles ,4.

a portion of the The inner hollows of the mold parts are formedcomplementary to shape the outer or exterior contour of the siphon headand the egress spout, and is in communication with a pouring gate 6 andthe principal air pipe 7 through which the air escapes when the metal isbeing cast into the mold. A

certain number of smaller air channels 8 are also provided.

The core is composed of five parts. A central base core 9, serving toproduce the inner hollow of the siphon head designed to embrace thebottle neck, has an end portion 10 corresponding to the shape of 'avalve seat. This core is provided with a concentric opening 12,extending from one ,-end to the other, communicating with a pipe 11,open to the air.

The base. core, through the pipe 11, is su ported by nuts 16 and ismovable longitu nally by the forked lever 13, the pivot means 14 ofwhich is carried by two supports 15 fixed to the underside ofthetable 1. The forked end of the lever 13 embraces pipe 11 and isconfined between adjustable nuts 16, in such .a manner that the basecore is normally retained in a position in operative relation to themold parts by the weight of the lever arm. The pipe 11 guided by a plate11 which is secured to support 11 ma be separated therefrom whereby thetaklng to pieces of the apparatus is greatly facilitated.

In order to form the central opening of the siphon head and lateralopenings, I provide a core 18, having a pro ection 17 of a size to entertheupper portion of the opening 12 in the core 9, and which is arrangedconcentrically therewith. The core 18 is provided with an opening 19through .which may be inserted a lateral core member'20 which serves toproduce a lateral opening in the siphon head for the operating lever Acurved core 24, the axis of which is concentric-with a pivot point 25,enters the complementary formed opening 2 of the mold parts 3' andserves to produce the inner bore of the siphon spout. The core 24 isguided through a confining plate 26 and is formed tapering toward thevertical axis of the siphon head. The core is secured, at its end 24*,to an arm 27 of an elbow lever 28 which is fork-shaped and pivot'allymounted on the bearings 25 carried by the supports 25. This lever, owingto its weight, returns the core 24 to an operative position with respectto the mold parts.

A suitable blow pipe 29 is provided for heating the mold and formaintaining the same at' a temperature near the point of fusion of thematerial of which the siphon head is to be formed. This blow pipe heatsthe entire plate and more particularly the cores 9 and 24:, the core 18being heated by its close proximity'with the melting furnace. Themold-parts rest upon the table by their own weight and are held inoperative relation with each other b means of a clamp 30 having portions30, ormed at ends, at

right angles to the main portion which is clamped together by a link 31orthe like.

From the above description it is seen that the castsiphon head isinclosed by the mold parts, which being complementally formed allows thecompleted product to be removed without injury to the same.

The operation of the device is as follows :-After the table 1 has beenmade stationary at a suitable distance from the melt ing furnace, thetable 1 and the cores 9 and 24 are heated by means ofthe blow pipe,while the mold parts are heated in a furnace. When the parts areperfectly clean and heated to the required temperature the mold partsare mounted on the table and the cores placed in their proper positionstherewith. The molding metal enters the mold-' ing machine through thepouring gate 6. When the required amount of metal has entered the devicethe cores 23 and '20 are removed from the core 18, which permits theremoval of the latter. Through the levers 13 and 28 the cores 9 and 24are removed. This allows the mold parts to be separated, the formedsiphon head remaining in one half thereof and removed therefrom by theoperator to the finishin table.

The manipulation o the device very simple and requires but a short timeto complete the cast siphon head and which enables the operatolarto'again assemble the device with very little loss of heat.
